Do you edit more than a few different podcasts?
I manage more than 20 shows – many of which use ID3 tags.
This is the process I found that works FASTEST:
1: Use ID3 Editor by PA-Software
2: Save the tag data for each show in a single DropBox folder
3: Load tag data to populate the majority of the data QUICKLY
Note: You can also save time from this process if uploading the mp3 to a libsyn account (use promo code FINCON for the first month free).
I show how in this video:
